Olav Haugan 77ba2b9f0b sched: Update task->on_rq when tasks are moving between runqueues
Task->on_rq has three states:
	0 - Task is not on runqueue (rq)
	1 (TASK_ON_RQ_QUEUED) - Task is on rq
	2 (TASK_ON_RQ_MIGRATING) - Task is on rq but in the
	process of being migrated to another rq

When a task is moving between rqs task->on_rq state should be
TASK_ON_RQ_MIGRATING in order for WALT to account rq's cumulative
runnable average correctly.  Without such state marking for all the
classes, WALT's update_history() would try to fixup task's demand
which was never contributed to any of CPUs during migration.
